There is currently no official exact flow rate value provided. However, in similar engine - cooling - pump applications, the flow rate generally ranges from 20 - 80 cubic meters per hour. This range is designed to meet the cooling requirements of the engine by ensuring an adequate amount of coolant is circulated through the system.
The actual flow rate can be affected by factors such as the pump's rotational speed and the resistance within the cooling circuit.
Head Pressure
For engine - cooling water pumps of this kind, the head pressure usually falls within the range of 8 - 30 meters. The working pressure generally does not exceed 0.8MPa. It's likely that the head pressure of this water pump also lies within this range.
Adequate head pressure is essential to overcome the resistance of the cooling system components, including hoses, radiators, and engine passages, to ensure efficient coolant circulation.
